Dating

Olivia Culpo and Danny Amendola may have forgotten old acquaintances -- at least one of them -- because it looks like they're back together.

Danny and Olivia each posted identical videos of fireworks to their IG stories ... videos obviously shot on New Year's Eve.

The videos were shot at a beach location, and the fact he plays for the Dolphins may be a geographical clue.

Olivia and Danny broke up a few months ago after he hit the beach with a super hot woman. After the pic surfaced, Olivia proclaimed she was keeping the $12,000 Rolex she bought for Danny's birthday.

If this is real, it will be the third time Danny and Olivia got together. They met in 2016, dated for 2 years, broke up, got back together last year but the woman in the bikini buzz killed that one. But, old flame don't douse easily.

Diddy might be missing his ex, Cassie, but she sure as hell ain't missing him ... not by the looks of this photo of her kissing another dude, anyway.

This one's tough to swallow if you're a Diddy/Cassie stan and had any hopes of them getting back together. Diddy posted an intimate shot of Cassie on his IG story Friday night ... and the same shot again early Saturday.

The message we're reading from this ... he's still got feelings.

Unfortunately for him, Cassie appears to have moved on with a younger man ... who she revealed on her own Insta account just hours after Diddy put up his tribute. Unclear if this was in direct response to that, but Cassie seems to be sending a message of her own.

The dude in question has reportedly been identified as fitness and health guru Alex Fine. As if the name isn't enough ... he's also a natural born stud. And, now ... Cassie's into him.

Interestingly enough, Cassie was seen with Diddy shortly after Kim Porter died last month ... which sparked rumors they might be rekindling their 10-year relationship following their October split.

Looks like that reunion was just moral support though, 'cause Cassie hasn't been spotted with Diddy since.

Pete Davidson is ending the year on a good note -- he's got a new haircut ... and, possibly, a new girl by his side.

The 'SNL' star was hanging out in Miami Saturday with a mystery girl at the Mandarin Oriental hotel, where eyewitnesses tell us they were chatting over lunch. Hard to tell who this chick is, but one thing's for sure ... Pete seems to be happy in her company.

It's been a rough year for Pete, so it's great to see he's enjoying himself to round out 2018 ... and going wherever the hell his heart desires.

You'll recall ... he was just in Cleveland last weekend watching Machine Gun Kelly's concert, and had the best seat in the house. He was covered up then, so we couldn't make out his new 'do. Now that we're seeing it in all its glory, we gotta say ... he looks fresh.

As for whether this was another date for Pete -- he recently went out to dinner with a previous mystery girl -- or just chillin' with a friend ... we simply don't know.

Corinne Olympios spent Xmas day enjoying the Miami Beach sun with her boyfriend.

The former "Bachelor" and "Bachelor in Paradise" contestant was hanging with Jon Yunger. She's been seeing him since May.

This pool encounter turned out a lot better than a previous outing last year, when Corinne accused DeMario Jackson of sexually assaulting her on the set of "Bachelor in Paradise." She claimed she was super drunk and did not give consent to the sexual contact. The allegation brought filming of "BIP" to a halt.

An investigation -- which included video of the encounter -- concluded Corrine was a willing participant and there was no sexual assault. Filming resumed, but Corrine and DeMario were no longer on the show.

Nicki Minaj's new boyfriend wasn't just convicted of attempted rape -- he also went to prison for killing a guy ... and now we know the story behind his manslaughter conviction.

Law enforcement sources tell TMZ ... Nicki's new man, Kenneth Petty, rolled up on Lamont Robinson one early morning in April 2002 and opened fire on him on a street corner in Queens, NY.

We're told Petty drove to the crime scene with a group of cohorts, hopped out of the car, walked across the street where Robinson was hanging out, pulled out a gun ... and shot him in the stomach 3 times. Our sources say he then fled in the vehicle with the group.

We're told police who investigated the crime at the time did not believe robbery was a motive -- they suspected it to be a targeted hit over a gang beef. One investigator who was on the OG case told us he could only recall the shooting was over some "bulls***."

According to court docs, obtained by TMZ, Lamont -- who only survived for a short time -- ID'd Kenneth in a photo lineup when police went to question him in the hospital. The docs say he nodded his head to confirm Kenneth had shot him, as he couldn't speak. He died soon afterward.

Kenneth was initially charged with 2nd-degree murder, but pled guilty to a lesser charge of 1st-degree manslaughter. He served 7 years in prison, and got released in 2013.

As we reported ... Nicki's beau also did nearly 4 years behind bars after being convicted of attempted rape as a 16-year-old about a decade prior.

Like we've told you, Nicki isn't fazed by Kenneth's checkered past ... as we're told, she and Kenneth have already discussed having babies and getting hitched.

Cardi B was all over Offset Friday ... hugging him and you might even say hanging on for dear life.

Cardi and Offset were vacationing in Puerto Rico, and it's a real sign his full-court campaign to win her back has worked.

Eyewitnesses tell TMZ they seemed very much like a couple as they laughed and played on and in the deep blue sea.

They were there with friends. No sign of baby Kulture, but it's a safe bet she's there.

Cardi has a set Friday night in San Juan at the Electric Holiday festival.

We don't know for sure if Cardi has taken Offset back, but there have been signs for more than a week that the ice is thawing.

Cardi announced her split with Offset on December 4. As we reported, he crashed her stage at the Rolling Loud Music Festival in L.A. last weekend, and she was clearly not receptive but it looks like things may have changed.

Nicki Minaj's new beau is the ultimate bad boy -- and has been for quite some time, including while he was behind bars.

Kenneth Petty's inmate disciplinary history, obtained by TMZ, shows Nicki's BF was written up 18 times from 2006 to 2013 while he was serving time for a manslaughter conviction in New York.

Some of Petty's violations were major -- he got slapped with 2 violent conduct violations in 2010 for threats and fighting. Before that, he also racked up another fighting violation, and 5 violations for disobeying a direct order.

He got off to a ROUGH start too ... just one day after he entered the prison he got tagged for creating a disturbance.

There was also a 2009 incident where he was cited for 9 separate violations, and got 4 months in solitary as punishment. Mostly though ... he lost phone, recreation and commissary privileges for bad behavior.

As you know, Minaj's BF was convicted of first-degree attempted rape in 1995 when he was 16. He served almost 4 years for that ... before the 2006 manslaughter conviction.

Still, the man did his time ... and our Nicki sources say she believes Kenny -- an old flame from Queens -- has changed, and she's happier than she's been in years.

Chris Pratt sending birthday love to his girlfriend, Katherine Schwarzenegger, was expected ... but he shocked us all by spilling the beans on his super cute nickname for her!!!

Chris posted an adorable bday message to Katherine on his Instagram, complete with a collage that screams #couplegoals ... but the thing that really caught our eye was the pet name, Chief.

The social media equivalent of a birthday card reads, "Happy Birthday Chief! Your smile lights up the room. I've cherished our time together. Thrilled God put you in my life. Thankful for the laughs, kisses, talks, hikes, love and care.

It's interesting ... as best we can tell, this is the first time Chris has ever shared a pic of Katherine on his social media pages. They've been having tons of fun together since the summer, from family football games on Thanksgiving to PDA sessions at Disneyland ... and now it's social media-official.

50 Cent has no problem with the pace Nicki Minaj and her new boyfriend seem to be moving at in their relationship ... because they're picking up right where they left off.

We got Fif in Bev Hills Wednesday night where, at first, we asked if he or Starz were planning anything for the family of the "Power" crew member who was tragically killed in a freak accident this week on set. Understandably, he's not ready to talk about it.

Our camera guy then pivots to the 'Queen' rapper, and asks if he thinks it's too soon for her to be talking babies and marriage with her new man/old flame, Kenneth Petty -- a convicted sex offender.

Nicki Minaj's relationship with her new boyfriend is way more serious than we thought -- 'cause we now know she's considering the married and mom life with him.

Sources close to the "Queen" MC tell us Nicki and Kenneth Petty have already had the marriage and baby talk -- this after only a couple months of dating. We're told Nicki is serious about the prospect of marrying Kenneth and having his kids ... because she believes he's that good a man.

As for that whole convicted sex offender thing -- among other crimes -- we're told Nicki couldn't care less.

She certainly isn't shy about showing off her new boo either -- Nicki posted a video of them working out together in the gym.

As we reported ... Nicki feels Kenneth has changed for the better since he was young -- when he was convicted of first-degree attempted rape as a 16-year-old. He's an old flame from back then, and we're told she's as happy as ever now that they've reconnected all these years later.

Nicki seems to believe Kenneth was falsely convicted ... he was dating the victim at the time and claims the girl's mother had it in for him and made false allegations.

Kiara Mia says there's no way in hell her date with Jimmy Garoppolo cursed the Niners QB ... but the porn star doesn't exactly mind the take, saying, "I'm flattered!"

Of course, Jimmy's season came to a catastrophic end just a few weeks after his famous night out with Kiara ... and some fans pegged her as the bad juju that caused his ACL tear.

But, Kiara says, for as much as she's honored that people think she has that kinda power -- she tells TMZ Sports it's just not possible.

"I'm impressed that people look at me as a God," Kiara says.

"Like, only God has the power to, like, control someone's journey in life. So, I'm flattered people think I have that much power in my life to control somebody's life!"

Kiara tells us she really hasn't been keeping up with Jimmy or his team -- we had to break the news to her that the Niners really suck -- but she says she's already moving on to a new squad.

"I'm Mexican and I'm from L.A., so I have to say the Raiders!"

Sooo ... Derek Carr, WYD???

Put him in, coach -- Pete Davidson's back playing the field after the Ariana Grande breakup, and we gotta say ... dude knows how to class it up for date night.

The 'SNL' vet was spotted having dinner 1-on-1 Monday night at Carbone in NYC, with a lovely lady sitting across from him. You can see in the pic, it was full wine and dine mode.

This is one of the first times we've seen Pete out on the town with a new girl since he and Ariana split in October and called off their engagement. We're told he has been casually dating. It's also certainly a nice change of pace considering how rocky things have been for him since the breakup, privately and publicly.

Just last week, he announced Internet trolls were encouraging him to kill himself ... but vowed he'd never do any such thing. Way to bounce back, Pete.

As they say ... thank u, next.

Ramona Singer and Harry Dubin are just friends -- friends who had one drunken makeout sesh -- but we're told they're definitely not banging ... not at this point.

Sources close to the kissing pals tell TMZ ... the 'RHONY' star and Dubin are not dating or even going the "friends with benefits" route. Despite the fact they were inhaling each other's faces Friday night in NYC, we're told there was nothing Biblical about how the night ended.

Translation: no nookie.

Our sources say Ramona and Harry were just talking and flirting and maybe definitely had too much to drink ... which led to the passionate kiss. We're told both are happily still single though.

As you 'Housewives' fans know ... Harry's got a long history with the 'Housewives' -- he's divorced from Aviva Drescher and is a former flame of Sonja Morgan and Luann de Lesseps.

If Nikki Bella's date with Peter Kraus had been filmed for "The Bachelorette," it would have ended with him strolling into an SUV without a rose. She just wasn't feeling it ... TMZ has learned.

Our production sources tell us ... while her date looked every bit like an episode of 'Bachelorette' -- which included a ride on a gondola and sipping wine -- fact is, there just weren't any sparks for her to wanna lock down a second date.

The big tell ... we're told Nikki couldn't muster the strength to pucker up and kiss Peter when he made his move. Yup, she left him hanging. We're told she freaked out and screamed "NO!!!" before pulling away.

Bottom line ... Nikki's just not ready to start dating again following her on-again, off-again relationship with John Cena.

As for why she went on the date at all? We're told Nikki's mom is a HUGE 'Bachelor' fan and suggested she give Peter a shot. The date will play out on the new season of "Total Bellas" next year.

For now, we're told Nikki will be laying low on the dating scene, and focusing on her career. Back to the drawing board, Peter.

Safaree's finally getting cozy with someone post-Nicki Minaj ... the rapper was spotted out and holding hands with Erica Mena.

Sources close to the 'Love & Hip Hop' stars tell TMZ ... Safaree and Erica recently started dating and ... were seen walking hand-in-hand IN MATCHING FUR COATS at the Jazz-Nets game Wednesday night at the Barclays Center in Brooklyn.

We're told there were immediate fireworks ... and while they're not officially boyfriend/girlfriend yet, they're well on their way to that status. Safaree had been hinting for a while now about finding love ... posting clues on his Instagram story he's riding with a new chick.

Erica also took to Twitter before the Nets game ... professing she's finally finding true love.

Our sources say Safaree and Erica's new connection will be featured on 'L&HH' at some point.

Clearly, these 2 kids seem to be riding high on Cloud 9 ... a far cry from their previous relationships. As you know ... Safaree's on-again, off-again relationship with Nicki Minaj ended terribly, to say the least. He most recently accused her of trying to kill him.

Could Tim Tebow's days as an unmarried man be numbered?!?!

Certainly seems that way ... 'cause the ex-NFL superstar brought his Miss Universe girlfriend to the Tebow Family Thanksgiving -- a sure sign that things are getting THAT serious.

Tim and Demi-Leigh Nel-Peters -- Miss Universe 2017 -- have been dating for a while now ... and they've been getting super cozy with each other the last few months.

Remember ... the South African model wished him a very public "happy birthday" back in August AND the two had a date day in New York with DLNP's fam in September.

In fact ... Demi even hinted she was "falling in love" with the minor league baseball star after the two hit up a Florida game last month.

But, the couple took things to another level last week ... when Tim brought her to the fam's turkey dinner.

"My first American style Thanksgiving with the sweetest family," DNLP said of the holiday ... "Grateful for an incredible year and everyone I got to share it with."

Tim never got a ring in his 3 years in the NFL ... but we wouldn't be shocked if he bought one pretty soon!!!
